The editor function is soooo handy for me as the owner of a web design business. It allows me to give the clients some independence to manage their site while retaining full Designer capabilities in my account.
However, most clients only get a Basic hosting plan that doesn't allow any editors. The price jump to CMS is alot for an editor feature.
I propose either adding a single editor seat on the Basic plan or adding an Editor Add-on for $2-3/month.
